Please stop with the libertarian slogans. It's not about ending your rights or those of the passersby. It's about a set of people being upset, and you wishing you were there - willing to go out of your way - to upset them further.
These people are upset with change. Hard luck to them, I never said their cause was just. But you antagonising them has nothing to do with anything but your own amusement. I wouldn't condone physical violence for you wearing a particular sweater - and if you notice, I never suggested that I did. I merely used your high-horse dismissive language against you: I would be unsympathetic to you should you run into trouble. If you went out of your way to antagonise aggressive, upset people just for your own jollies, I'm not going to coddle you and say "there there, poor guy, those mean protesters".
If a kid sticks a knife into a power socket and gets seriously hurt, I'll be sympathetic. But if an adult does a Jackass-style "won't this be fun!" version and gets seriously hurt, no, I won't be sympathetic. I'll call an ambulance and apply first aid, but why should I care how that adult feels because they got hurt knowingly doing something stupid?
Also, how sympathetic would you feel towards a Black man who "antagonized" white people by passing through a White neighborhood
"I wish I knew about this [so I could go and antagonise them]" is not merely 'passing through'.
